How to use

There are 3 images: latest, auto and naked.

sickcodes/docker-osx:latest - I want to try it out.

sickcodes/docker-osx:latest - I want to use Docker-OSX to develop/secure Apps in Xcode (sign into Xcode, Transporter)

sickcodes/docker-osx:naked - I want to use Docker-OSX in CI/CD (sign into Xcode, Transporter) Create your personal image using :latest. And then pull your image out. And then use duplicate that image again & again for use in :naked.

sickcodes/docker-osx:auto - I want to boot into command line only. (compile software, homebrew headless).

sickcodes/docker-osx:naked - I need iMessage/iCloud for security research.

I need a screen.

KEEP these two lines are in your command. Works in ANY of the machines:

    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e "DISPLAY=${DISPLAY:-:0.0}" \

I need headless.

REMOVE these two lines from ANY of the machines:

    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e "DISPLAY=${DISPLAY:-:0.0}" \

I have used it already, and want to copy this image.

Use docker commit, copy the ID, and then docker start ID

OR

Pull out the .img file, and then use that .img file with :naked

Basic Quick Start Docker-OSX

docker pull sickcodes/docker-osx:latest

# catalina
docker run -it \
    --device /dev/kvm \
    -p 50922:10022 \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
    sickcodes/docker-osx:latest

# big sur
docker run -it \
    --device /dev/kvm \
    -p 50922:10022 \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
    sickcodes/docker-osx:big-sur

# Wait 2-3 minutes until you see the logo.

Quick Start Large Pre-Made Image

Current large image size: 17.5GB

This starts a container with an existing installation. This special auto image was made by @sickcodes:

• SSH enabled
• username is user
• password is alpine
• auto-updates off

You will need around 50GB of space to run this image: half for the base image + half for your runtime image.

If you run out of space, you can delete all your old Docker images/history/cache by simply deleting /var/lib/docker, and restarting dockerd.

docker pull sickcodes/docker-osx:auto

# boot directly into a real OSX shell with no display (Xvfb) [HEADLESS]
docker run -it \
    --device /dev/kvm \
    -p 50922:10022 \
    sickcodes/docker-osx:auto

# Wait 2-3 minutes until you drop into the shell.

docker pull sickcodes/docker-osx:auto

# boot directly into a real OSX shell with a visual display [NOT HEADLESS]
docker run -it \
    --device /dev/kvm \
    -p 50922:10022 \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
    sickcodes/docker-osx:auto

Pre-built Image + Arbitrary Command Line Arguments.

docker pull sickcodes/docker-osx:auto

# boot to OSX shell + display + specify commands to run inside OSX!
docker run -it \
    --device /dev/kvm \
    -p 50922:10022 \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
    -e "OSX_COMMANDS=/bin/bash -c \"pwd && uname -a\"" \
    sickcodes/docker-osx:auto

# Boots in a minute or two!

Restart an auto container

Containers that use sickcodes/docker-osx:auto can be stopped at started.

# find last container
docker ps -a

# docker start old container with -i for interactive
docker start -i containerid

Quick Start Own Image (naked container image)

This is my favourite container. You can supply an existing disk image as a docker command line argument.

Supply your own local image with -v "${PWD}/mac_hdd_ng.img:/image" and use sickcodes/docker-osx:naked

• Naked image is for booting any existing .img file.
• By default, this image has a variable called NOPICKER which is "true". This skips the disk selection menu. Use -e NOPICKER=false or any other string than the word true to enter the boot menu. This lets you use other disks instead of skipping the boot menu, e.g. recovery disk or disk utility.

docker pull sickcodes/docker-osx:naked

# run your own image + SSH
# change mac_hdd_ng.img
docker run -it \
    --device /dev/kvm \
    -p 50922:10022 \
    -v "${PWD}/mac_hdd_ng.img:/image" \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
    sickcodes/docker-osx:naked

# run local copy of the auto image + SSH + Boot menu
docker run -it \
    --device /dev/kvm \
    -p 50922:10022 \
    -v "${PWD}/mac_hdd_ng_auto.img:/image" \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
    -e "NOPICKER=false" \
    sickcodes/docker-osx:naked

Fully Headless, using my own image, for CI/CD

# run your own image headless + SSH
docker run -it \
    --device /dev/kvm \
    -p 50922:10022 \
    -v "${PWD}/mac_hdd_ng.img:/image" \
    sickcodes/docker-osx:naked

Download The Image for sickcodes/docker-osx:naked

This is the current automated image. Username is user, passsword is alpine, SSH is on, and auto-updates are off.

If the download is slow, just get the image from docker pull sickcodes/docker-osx:auto and find it in /var/lib/docker.

wget https://images2.sick.codes/mac_hdd_ng_auto.img

docker run -it \
    --device /dev/kvm \
    -p 50922:10022 \
    -v "${PWD}/mac_hdd_ng_auto.img:/image" \
    -v /tmp/.X11-unix:/tmp/.X11-unix \

# turn on SSH after you've installed OSX in the "Sharing" settings.
ssh fullname@localhost -p 50922

Autoboot into OSX after you've installed everything

You can use -e NOPICKER=true.

Old machines:

# find you containerID
docker ps

# move the no picker script on top of the Launch script
# NEW CONTAINERS
docker exec containerID mv ./Launch-nopicker.sh ./Launch.sh

# VNC-VERSION-CONTAINER
docker exec containerID mv ./Launch-nopicker.sh ./Launch_custom.sh

# LEGACY CONTAINERS
docker exec containerID bash -c "grep -v InstallMedia ./Launch.sh > ./Launch-nopicker.sh
chmod +x ./Launch-nopicker.sh
sed -i -e s/OpenCore\.qcow2/OpenCore\-nopicker\.qcow2/ ./Launch-nopicker.sh
"

Requirements: KVM on the host

Need to turn on hardware virtualization in your BIOS, very easy to do.

Then have QEMU on the host if you haven't already

# ARCH
sudo pacman -S qemu libvirt dnsmasq virt-manager bridge-utils flex bison iptables-nft edk2-ovmf

# UBUNTU DEBIAN
sudo apt install qemu qemu-kvm libvirt-clients libvirt-daemon-system bridge-utils virt-manager

# CENTOS RHEL FEDORA
sudo yum install libvirt qemu-kvm

# then run
sudo systemctl enable libvirtd.service
sudo systemctl enable virtlogd.service

echo 1 | sudo tee /sys/module/kvm/parameters/ignore_msrs

sudo modprobe kvm

# reboot

Start the same container later (persistent disk)

1. You can now pull the .img file out of the container, which is stored in /var/lib/docker, and supply it as a runtime argument to the :naked Docker image. See above.

2. This is for when you want to run the SAME container again later.

If you don't run this you will have a new image every time.

# look at your recent containers and copy the CONTAINER ID
docker ps --all

# docker start the container ID
docker start abc123xyz567

# if you have many containers, you can try automate it with filters like this
# docker ps --all --filter "ancestor=sickcodes/docker-osx"
# for locally tagged/built containers
# docker ps --all --filter "ancestor=docker-osx"

Additional Boot Instructions

• Boot the macOS Base System

• Click Disk Utility

• Erase the BIGGEST disk (around 200gb default), DO NOT MODIFY THE SMALLER DISKS. -- if you can't click erase, you may need to reduce the disk size by 1kb

• (optional) Create a partition using the unused space to house the OS and your files if you want to limit the capacity. (For Xcode 12 partition at least 60gb.)

• Click Reinstall macOS

Creating images:

# You can create an image of an already configured and setup container.
# This allows you to effectively duplicate a system.
# To do this, run the following commands

# make note of your container id
docker ps --all
docker commit containerid newImageName

# To run this image do the following
docker run \
    --device /dev/kvm \
    --device /dev/snd \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    newImageName

PulseAudio for sound (note neither AppleALC and varying alcid or VoodooHDA-OC have codec support though IORegistryExplorer does show the controller component working):

docker run \
    --device /dev/kvm \
    -e AUDIO_DRIVER=pa,server=unix:/tmp/pulseaudio.socket \
    -v "/run/user/$(id -u)/pulse/native:/tmp/pulseaudio.socket" \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    sickcodes/docker-osx

PulseAudio debugging:

docker run \
    --device /dev/kvm \
    -e AUDIO_DRIVER=pa,server=unix:/tmp/pulseaudio.socket \
    -v "/run/user/$(id -u)/pulse/native:/tmp/pulseaudio.socket" \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e PULSE_SERVER=unix:/tmp/pulseaudio.socket \

Check if your hardware virt is on

egrep -c '(svm|vmx)' /proc/cpuinfo

Try adding yourself to the docker group

sudo usermod -aG docker "${USER}"

Turn on docker daemon

# run ad hoc
sudo dockerd

# or daemonize it
sudo nohup dockerd &

# or enable it in systemd
sudo systemctl enable docker

How to Forward Additional Ports from the guest.

This is how it visually looks:

host:10023 <-> 10023:container:10023 <-> 80:guest

On the host
```bash
docker run -it \
    --device /dev/kvm \
    -p 50922:10022 \
    -e ADDITIONAL_PORTS='hostfwd=tcp::10023-:80,' \
    -p 10023:10023 \
    sickcodes/docker-osx:auto

Inside the container:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

brew install nginx
sudo sed -i -e 's/8080/80/' /usr/local/etc/nginx/nginx.confcd
# sudo nginx -s stop
sudo nginx

nginx should appear on the host at port 10023.

You can string multiple statements, for example:

    -e ADDITIONAL_PORTS='hostfwd=tcp::10023-:80,hostfwd=tcp::10043-:443,'
    -p 10023:10023 \
    -p 10043:10043 \

How to Enable Network Forwarding

Allow ipv4 forwarding for bridged networking connections:

This is not required for LOCAL installations and may cause containers behind VPN's to leak host IP.

If you are connecting to a REMOTE Docker-OSX, e.g. a "Mac Mini" in a datacenter, then this may boost networking:

# enable for current session
sudo sysctl -w net.ipv4.ip_forward=1

# OR
# sudo tee /proc/sys/net/ipv4/ip_forward <<< 1

# enable permanently
sudo touch /etc/sysctl.conf
sudo tee -a /etc/sysctl.conf <<EOF
net.ipv4.ip_forward = 1
EOF

# OR edit manually
nano /etc/sysctl.conf || vi /etc/sysctl.conf || vim /etc/sysctl.conf

# now reboot

How to install Docker if you don't have Docker already

### Arch
sudo pacman -S docker
sudo groupadd docker
sudo usermod -aG docker "${USER}"

### Ubuntu

sudo apt remove docker docker-engine docker.io containerd runc -y
sudo apt install apt-transport-https ca-certificates curl gnupg-agent software-properties-common -y
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
apt-key fingerprint 0EBFCD88
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt update -y
sudo apt install docker-ce docker-ce-cli containerd.io -y
sudo groupadd docker
sudo usermod -aG docker "${USER}"

Fedora: if you have no internet connectivity from the VM, and you are using bridge networking:

# Set the docker0 bridge to the trusted zone
sudo firewall-cmd --permanent --zone=trusted --add-interface=docker0
sudo firewall-cmd --reload

Backup the disk (Where's my disk?)

You can use docker cp

# docker copy your image OUT of your container (warning, double disk space)
docker cp oldcontainerid:/home/arch/OSX-KVM/mac_hdd_ng.img .

Or if you lost your container, find it with this:

# fast way, find 10 gigabyte OSX disks hiding in your docker container storage
sudo find /var/lib/docker -size +10G | grep mac_hdd_ng.img

# you can move (mv) it somewhere, using cp can take loads of disk space
sudo mv somedir/mac_hdd_ng.img .

Use an Old Docker-OSX Disk in a Fresh Container (Replication)

Use the sickcodes/docker-osx:naked image.

Internet Speeds

FAST internet

-e NETWORKING=vmxnet3

SLOW internet

-e NETWORKING=e1000-82545em

DESTROY: Wipe old images to free disk space

The easiest way to clean out your entire Docker (ALL images, layers, and containers) is to sudo rm -rf /var/lib/docker

This is useful for getting disk space back.

It will delete ALL your old (and new) docker containers.

# WARNING deletes all old images, but saves disk space if you make too many containers
# The following command will make your containers RIP
docker system prune --all
docker image prune --all

CI/CD Related Improvements

How to reduce the size of the image

• Start up the container as usual, and remove unnecessary files. A useful way to do this is to use du -sh * starting from the / directory, and find large directories where files can be removed. E.g. unnecessary cached files, Xcode platforms, etc.
• Once you are satisfied with the amount of free space, enable trim with sudo trimforce enable, and reboot.
• Zero out the empty space on the disk with dd if=/dev/zero of=./empty && rm -f empty
• Shut down the VM and copy out the qcow image with docker cp stoppedcontainer:/home/arch/OSX-KVM/mac_hdd_ng.img .
• Run qemu-img check -r all mac_hdd_ng.img to fix any errors.
• Run qemu-img convert -O qcow2 mac_hdd_ng.img deduped.img and check for errors again
• OPTIONAL: Run qemu-img convert -c -O qcow2 deduped.img compressed.img to further compress the image. This may reduce the runtime speed though, but it should reduce the size by roughly 25%.
• Check for errors again, and build a fresh docker image. E.g. with this Dockerfile

FROM sickcodes/docker-osx
USER arch
COPY --chown=arch ./deduped.img /home/arch/OSX-KVM/mac_hdd_ng.img

How to run in headless mode

First make sure autoboot is enabled

Next, you will want to set up SSH to be automatically started.

sudo systemsetup -setremotelogin on

Make sure to commit the new docker image and save it, or rebuild as described in the section on reducing disk space.

Then run it with these arguments.

# Run with the -nographic flag, and enable a telnet interface
  docker run \
    --device /dev/kvm \
    -p 50922:10022 \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
    -e EXTRA="-monitor telnet::45454,server,nowait -nographic -serial null" \
    mycustomimage

Optionally, you can enable the SPICE protocol, which allows you to use remote-viewer to access it rather than VNC.

Note: -disable-ticketing will allow unauthenticated access to the VM. See the spice manual for help setting up authenticated access ("Ticketing").

  docker run \
    --device /dev/kvm \
    -p 50922:10022 \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
    -e EXTRA="-monitor telnet::45454,server,nowait -nographic -serial null -spice disable-ticketing,port=3001" \
    mycustomimage

Then simply do remote-viewer spice://localhost:3001 and add --spice-debug for debugging.

Custom Build or Local Development

If you are building Docker-OSX locally, you will want to use Arch Linux mirrors.

Mirror locations can be found here (use 2 letter country codes): https://archlinux.org/mirrorlist/all/

docker build -t docker-osx:latest \
    --build-arg RANKMIRRORS=true \
    --build-arg MIRROR_COUNTRY=US \
    --build-arg MIRROR_COUNT=10 \
    --build-arg VERSION=10.15.6 \
    --build-arg SIZE=200G .

Custom QEMU Arguments (passthrough devices)

Pass any devices/directories to the Docker container & the QEMU arguments using the handy -e EXTRA= runtime options.

# example customizations
docker run \
    -e RAM=4 \
    -e SMP=4 \
    -e CORES=4 \
    -e EXTRA='-usb -device usb-host,hostbus=1,hostaddr=8' \
    -e INTERNAL_SSH_PORT=23 \
    -e MAC_ADDRESS="$(xxd -c1 -p -l 6 /dev/urandom | tr '\n' ':' | cut -c1-17)" \
    -e AUDIO_DRIVER=alsa \
    -e IMAGE_PATH=/image \
    -e SCREEN_SHARE_PORT=5900 \
    -e DISPLAY=:0 \
    -e NETWORKING=vmxnet3 \
    --device /dev/kvm \
    --device /dev/snd \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    docker-osx:latest

Serial Numbers

The easiest way to show you is by these examples.

For serial numbers, generate them in ./custom OR make docker generate them at runtime (see below).

At any time, verify your serial number before logging in iCloud, etc.

# this is a quick way to check your serial number via cli inside OSX
ioreg -l | grep IOPlatformSerialNumber

# or from the host
sshpass -p 'alpine' ssh user@localhost -p 50922 'ioreg -l | grep IOPlatformSerialNumber'

This example generates a random set of serial numbers at runtime, headlessly

# proof of concept only, generates random serial numbers, headlessly, and quits right after.
docker run --rm -it \
    --device /dev/kvm \
    -p 50922:10022 \
    -e NOPICKER=true \
    -e GENERATE_UNIQUE=true \
    -e DEVICE_MODEL="iMacPro1,1" \
    -e OSX_COMMANDS='ioreg -l | grep IOPlatformSerialNumber' \
    sickcodes/docker-osx:auto

This example generates a specific set of serial numbers at runtime

# run the same as above 17gb auto image, with SSH, with nopicker, and save the bootdisk for later.
# you don't need to save the bootdisk IF you supply specific serial numbers!
touch ./C02TW0WAHX87.qcow

docker run -it \
    --device /dev/kvm \
    -p 50922:10022 \
    -e NOPICKER=true \
    -e GENERATE_SPECIFIC=true \
    -e DEVICE_MODEL="iMacPro1,1" \
    -e SERIAL="C02TW0WAHX87" \
    -e BOARD_SERIAL="C027251024NJG36UE" \
    -e UUID="5CCB366D-9118-4C61-A00A-E5BAF3BED451" \
    -e MAC_ADDRESS="A8:5C:2C:9A:46:2F" \
    -e OSX_COMMANDS='ioreg -l | grep IOPlatformSerialNumber' \
    sickcodes/docker-osx:auto

This example generates a specific set of serial numbers at runtime, with your existing image, at 1000x1000 display resolution.

# run an existing image in current directory, with a screen, with SSH, with nopicker, and save the bootdisk for later.

stat mac_hdd_ng.img # make sure you have an image if you're using :naked
touch ./mynewbootdisk.qcow

docker run -it \
    --device /dev/kvm \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -p 50922:10022 \
    -e NOPICKER=true \
    -e GENERATE_SPECIFIC=true \
    -e DEVICE_MODEL="iMacPro1,1" \
    -e SERIAL="C02TW0WAHX87" \
    -e BOARD_SERIAL="C027251024NJG36UE" \
    -e UUID="5CCB366D-9118-4C61-A00A-E5BAF3BED451" \
    -e MAC_ADDRESS="A8:5C:2C:9A:46:2F" \
    -e WIDTH=1000 \
    -e HEIGHT=1000 \
    -e BOOTDISK=/bootdisk \
    -v "${PWD}/mynewbootdisk.qcow:/bootdisk" \
    -v "${PWD}/mac_hdd_ng.img:/image" \
    sickcodes/docker-osx:naked

If you want to generate serial numbers, either make them at runtime using -e GENERATE_UNIQUE=true \

Or you can generate them inside the ./custom folder. And then use:

    -e GENERATE_SPECIFIC=true \
    -e SERIAL="" \
    -e BOARD_SERIAL="" \
    -e UUID="" \
    -e MAC_ADDRESS="" \

Persistence from generating serial numbers is obviously ideal:

stat mac_hdd_ng_testing.img
touch ./output.qcow 
touch ./output.env

# generate fresh random serial numbers, with a screen, using my own image, and save the bootdisk AND env file with my new serial numbers for later.

docker run -it \
    --device /dev/kvm \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -p 50922:10022 \
    -e NOPICKER=true \
    -e GENERATE_UNIQUE=true \
    -e GENERATE_SPECIFIC=true \
    -e DEVICE_MODEL="iMacPro1,1" \
    -e BOOTDISK=/bootdisk \

To use iMessage or iCloud you need to change 5 values.

SERIAL

BOARD_SERIAL

UUID

MAC_ADDRESS

ROM is just the lowercased mac address, without : between each word.

You can tell the container to generate them for you using -e GENERATE_UNIQUE=true

Or tell the container to use specific ones using -e GENERATE_UNIQUE=true

    -e GENERATE_SPECIFIC=true \
    -e DEVICE_MODEL="iMacPro1,1" \
    -e SERIAL="C02TW0WAHX87" \
    -e BOARD_SERIAL="C027251024NJG36UE" \
    -e UUID="5CCB366D-9118-4C61-A00A-E5BAF3BED451" \
    -e MAC_ADDRESS="A8:5C:2C:9A:46:2F" \

Where do you get the serial numbers?

apt install libguestfs -y
pacman -S libguestfs
yum install libguestfs -y

Inside the ./custom folder you will find 4 scripts.

• config-nopicker-custom.plist
• opencore-image-ng.sh These two files are from OSX-KVM.

You don't need to touch these two files.

The config.plist has 5 values replaced with placeholders. Click here to see those values for no reason.

• generate-unique-machine-values.sh This script will generate serial numbers, with Mac Addresses, plus output to CSV/TSV, plus make a bootdisk image.

You can create hundreds, ./custom/generate-unique-machine-values.sh --help

./custom/generate-unique-machine-values.sh \
    --count 1 \
    --tsv ./serial.tsv \
    --bootdisks \
    --output-bootdisk OpenCore.qcow2 \
    --output-env source.env.sh

Or if you have some specific serial numbers...

• generate-specific-bootdisk.sh

generate-specific-bootdisk.sh \
    --model "${DEVICE_MODEL}" \
    --serial "${SERIAL}" \
    --board-serial "${BOARD_SERIAL}" \
    --uuid "${UUID}" \
    --mac-address "${MAC_ADDRESS}" \
    --output-bootdisk OpenCore-nopicker.qcow2

Change Resolution Docker-OSX - change resolution OpenCore OSX-KVM

The display resolution is controlled by this line:

https://github.com/sickcodes/Docker-OSX/blob/master/custom/config-nopicker-custom.plist#L819

Instead of mounting that disk, Docker-OSX will generate a new OpenCore.qcow2 by using this one cool trick:

-e GENERATE_UNIQUE=true \
-e WIDTH=800 \
-e HEIGHT=600 \

To use WIDTH/HEIGHT, you must use with either -e GENERATE_UNIQUE=true or -e GENERATE_SPECIFIC=true.

It will take around 30 seconds longer to boot because it needs to make a new boot partition using libguestfs.

-e GENERATE_SPECIFIC=true \
-e WIDTH=1920 \
-e HEIGHT=1080 \
-e SERIAL="" \
-e BOARD_SERIAL="" \
-e UUID="" \
-e MAC_ADDRESS="" \

Change Docker-OSX Resolution Examples

# using an image in your current directory
stat mac_hdd_ng.img

    --device /dev/kvm \
    -p 50922:10022 \
    -v "${PWD}/mac_hdd_ng.img:/image" \
    -v /tmp/.X11-unix:/tmp/.X11-unix \

    sickcodes/docker-osx:naked

# generating random serial numbers, using the DIY installer, along with the screen resolution changes.
docker run -it \

    -e GENERATE_UNIQUE=true \
    -e WIDTH=800 \
    -e HEIGHT=600 \
    sickcodes/docker-osx:latest

Here's a few other resolutions! If you resolution is invalid, it will default to 800x600.

    -e WIDTH=800 \
    -e HEIGHT=600 \

    -e WIDTH=1280 \
    -e HEIGHT=768 \

    -e WIDTH=1600 \
    -e HEIGHT=900 \

    -e WIDTH=1920 \
    -e HEIGHT=1080 \

    -e WIDTH=2560 \
    -e HEIGHT=1600 \

Allow USB passthrough

The simplest way to do this is the following:

First of all, in order to do this, QEMU must be started as root. It is also potentially possible to do this by changing the permissions of the device in the container. See here.

For example, create a new Dockerfile with the following

FROM sickcodes/docker-osx
USER arch
RUN sed -i -e s/exec\ qemu/exec\ sudo\ qemu/ ./Launch.sh
COPY --chown=arch ./new_image.img /home/arch/OSX-KVM/mac_hdd_ng.img

Where new_image.img is the qcow2 image you extracted. Then rebuild with docker build .

Find out the bus and port numbers of your USB device which you want to pass through to the VM.

lsusb -t
/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/12p, 480M
    |__ Port 2: Dev 5, If 0, Class=Human Interface Device, Driver=usbhid, 12M
    |__ Port 2: Dev 5, If 1, Class=Chip/SmartCard, Driver=, 12M
    |__ Port 3: Dev 2, If 0, Class=Wireless, Driver=, 12M
    |__ Port 3: Dev 2, If 1, Class=Wireless, Driver=, 12M
    |__ Port 5: Dev 3, If 0, Class=Video, Driver=uvcvideo, 480M
    |__ Port 5: Dev 3, If 1, Class=Video, Driver=uvcvideo, 480M

In this example, we want to pass through a smartcard device. The device we want is on bus 1 and port 2.

There may also be differences if your device is usb 2.0 (ehci) vs usb 3.0 (xhci). See here for more details.

# hostbus and hostport correspond to the numbers from lsusb
# runs in privileged mode to enable access to the usb devices.
docker run \
  --privileged \
  --device /dev/kvm \
  -e RAM=4 \
  -p 50922:10022 \
  -e "DISPLAY=${DISPLAY:-:0.0}" \
  -e EXTRA="-device virtio-serial-pci -device usb-host,hostbus=1,hostport=2" \
  mycustomimage

You should see the device show up when you do system_profiler SPUSBDataType in the MacOS shell.

Important Note: this will cause the host system to lose access to the USB device while the VM is running!

What is ${DISPLAY:-:0.0}?

$DISPLAY is the shell variable that refers to your X11 display server.

${DISPLAY} is the same, but allows you to join variables like this:

• e.g. ${DISPLAY}_${DISPLAY} would print :0.0_:0.0
• e.g. $DISPLAY_$DISPLAY would print :0.0

...because $DISPLAY_ is not $DISPLAY

${variable:-fallback} allows you to set a "fallback" variable to be substituted if $variable is not set.

You can also use ${variable:=fallback} to set that variable (in your current terminal).

In Docker-OSX, we assume, :0.0 is your default $DISPLAY variable.

You can see what yours is

echo $DISPLAY

Hence, ${DISPLAY:-:0.0} will use whatever variable your X11 server has set for you, else :0.0

What is -v /tmp/.X11-unix:/tmp/.X11-unix?

-v is a Docker command-line option that lets you pass a volume to the container.

The directory that we are letting the Docker container use is a X server display socket.

/tmp/.X11-unix

If we let the Docker container use the same display socket as our own environment, then any applications you run inside the Docker container will show up on your screen too! https://www.x.org/archive/X11R6.8.0/doc/RELNOTES5.html
